Eric Dickerson has vivid memories of Halloween in 1987, and having his best costume ever was only one reason.

"I was in my kitchen," Dickerson says. "Myself, a friend of mine and Jim Gray. And I was about to walk out. They kept going, 'Let's go, let's go.' I'm like, 'OK, give me a minute.' The phone rings. It was Ron Meyer telling me I'd been traded to the Colts."
